Two Glycosides and Other Constituents from Anemone tomentosa Roots

Two new natural products, i.e. , 1‐ O ,2‐ O ‐[(1 S ,2 S )‐1‐(3‐acetyl‐2,4,6‐trihydroxyphenyl)‐3‐hydroxypropane‐1,3‐diyl]‐ β ‐ D ‐glucopyranose (=tomentoside I; 1 ) and (3 β )‐3‐(acetyloxy)ferruginol 12‐[6‐ O ‐(4‐hydroxy‐3,5‐dimethoxybenzoyl)‐ β ‐ D ‐glucopyranoside] (=tomentoside II; 2 ), were isolated from the EtOH extract of the root of Anemone tomentosa , together with five known compounds. Their structures were characterized by means of spectroscopic methods, especially by 1 H‐, 13 C‐, and 2D‐NMR and HR‐MS, as well as by chemical methods and comparison with literature data.
